I wish I could give this game a much higher score, but after dealing with multiple little bugs, such as restarting the game because the dialogue icon wouldn't work after awhile, I finally reached a massive game breaking bug. The game was decent enough but the issues I had detracted from the experience. Without giving away too much for those who still want to try, my party ended up in one plane towards the end of the game with no way to get back to civilization. The NPC who creates a portal for you just disappeared from the screen -- no chance for dialogue, no death, no portal opening, nothing. There is no way to advance the story beyond this point. It looks like I'm going to have to resort to watching a 'Let's play' to see how the story ends. It's a bit of a bummer, though, because I wanted to play through on my own. TL;DR -- I wouldn't recommend Linux users buy this. The bugs outweigh a somewhat decent game.
